Batteries supply power to portable electronic devices by converting chemical energy into electrical energy. The following are a few types of batteries available at retail stores.

Primary Cell Battery - A disposable battery used in devices with low energy requirements or devices that are stored for long periods. Primary cell batteries are useful for items like flashlights that are not used regularly because they do not lose charge as quickly as rechargeable batteries when stored.

Rechargeable Battery - A battery used in devices with high energy requirements that can be recharged and reused. Rechargeable batteries are used to power laptops and cell phones because of their high energy needs and frequent use. Rechargeable batteries are often more expensive than disposable ones, but since they do not need to be replaced as often, they result in long-term savings.

Lithium Batteries - Disposable or rechargeable batteries made with lithium that are long lasting and lose charge slowly. Lithium batteries are used to power electronics that are not designed for customers to replace the batteries. They are also used in devices like pacemakers because of their long life.

Car Battery - A battery used to power the starter, lights, radio, and ignition of an automobile. Car batteries recharge themselves, so they do not need to be replaced frequently. Some retail stores that sell car batteries give discounts to customers who bring in their old car battery for recycling.

Button Cell Battery - A small circular battery used in devices like watches and hearing aids. Button cells come in several sizes and are typically disposable.
